First Quarter 2003 Groundwater Monitoring/Remediation Status Report <br /> ! [ Moore Petroleum Bulk Plant,5491 F Street,Banta,California <br /> ffrrrr�� Page 5 <br /> Modifications from Standard Monitoring Program: <br /> None <br /> REMEDIATION SYSTEM SUMMARY' - <br /> 1 Soil Vapor Extraction System <br /> System description: <br /> Gasoline vapors are extracted .from the subsurface through three monitonng/vapor wells (VEW- <br /> 3/MW-8, MW-1, and VEW-4/MW-7) and two vapor extraction wells (VEW-1 and VEW-2). The ' <br /> wells are manifolded together with PVC piping in the remediation compound before connecting <br /> t to the extraction system (Figure 2). The vapor extraction system is a King Buck®, 100 cfm, <br /> catalytic oxidizer model No. MMC-5A, utilizing a positive-displacement blower as a vacuum <br /> ' k <br /> source. <br /> System startup date: June 17, 2002 <br /> Current system mode: Catalytic operation since startup. r <br /> Active extraction wells: VEW-1 through-VEW-4 <br /> i <br /> Inactive extraction wells/reason: MW-1 <br /> . a <br /> Status of system operation during reporting period/reasons for downtime: <br /> During this reporting period, from December 27, 2002, to-March 25, 2003, the SVE system did <br /> not operate,continuously. According to hour meter readings and held data reported by Apex <br /> personnel the system operated a total of 58.5 days. On January 8, Apex shut the SVE system off <br /> for a quarterly monitoring event and restarted the system on January.10, 2003. Also, the SVE <br /> system was found shut down upon arrival on January 24, and February 10 due to water <br /> 4 <br /> accumulation in-the knockout drum. The system vacuum was lowered to reduce the amount of <br /> 'r water being pulled from the subsurface. <br /> Table `5 summarizes extraction and. emission data from sampling events that are normally <br /> performed at. the beginning of each month. The flow rates and analytical data.are used to <br /> calculate approximate pounds -of hydrocarbons extracted and averaged between the sampling <br /> events to form the following results. <br /> System performance totals: <br /> Pounds of TPH removed: 1,676 pounds (266 gallons) this.quarter/ l <br /> 3,912 pounds (621 gallons) total <br /> Pounds of benzene removed: 0.2 pounds this quarter/1-.4'pounds'total <br />
